I'd say raising the rate at which you recieve Zeni is fine an all, but still requiring people to so that many P-dubs is "we todd did". I'd suggest raising the zeni, for sure, but at the same time, make the requirement more like killing P-dub 3x, not 10 items, 5 items, or even 1 item, unless those items are going to be in pouches like the heavy metal plates are (where you're guaranteed at least 5, but a max of 15)
